The New Year brings new features, functionality and simplicity for organizations deploying Hadoop solutions based on the latest release of Cloudera Enterprise. With the launch of Cloudera Enterprise 5.5, big data teams can now get more of the things that matter most to them—notably, better performance, enhanced security and advanced analytics.
New features in Cloudera Enterprise 5.5 include the limited beta release of Cloudera Navigator Optimizer for improved workload performance and efficiency. Navigator Optimizer enables a full optimization strategy for Hadoop environments. It instantly analyzes existing workloads and provides visibility into the workloads that are the most critical. It shows the data that is accessed most often and how that data is being used. This information can help organizations address the pervasive problem of inefficiently allocated data workloads.
Other enhancements in Cloudera Enterprise 5.5 include new capabilities to empower analytics on complex data in Hadoop. With that objective in mind, Impala now supports nested data types for expanded data discovery and business intelligence.
To enable secure analytics across an entire business, Impala now incorporates column-level security for fine-grained access controls for all users. For additional protection, Cloudera Enterprise now also provides credential management capabilities, including password redaction. These advances continue the ongoing maturation of security capabilities in the Hadoop platform, which now offers enterprise-class security features.
On the simplicity front, Cloudera Enterprise 5.5 contains a number of improvements related to deeper integration with HUE—the open source GUI that makes Hadoop easier to use. These improvements include easier setup for HUE HA, built-in activity monitoring for improved stability and better security and reporting via Cloudera Navigator and Apache Sentry.
At Dell, meanwhile, we continue our work to simplify Hadoop deployment and upgrades. In that spirit, we’ve updated our reference architectures, as well as our QuickStart proof of concept bundle, to use a single server model in Cloudera Enterprise 5.5 configurations. We’re now using the Dell PowerEdge R730xd server for both infrastructure and data nodes.
The use of a single server model for all nodes, rather than different models for the different types of nodes, will simplify logistics for our customers. We’re now using the same chassis for all nodes—adjusting only the drives. This will lead to simpler setup and maintenance, simpler spare inventory and simpler ordering templates.
This is all good news for organizations that are building big data environments on the Hadoop platform. With the launch of Cloudera Enterprise 5.5 and a simplified Dell stack, Hadoop environments are easier to deploy and optimize, more secure and better poised to take on the big data opportunities that the New Year will bring.
